GCC header map lists some private headers as public

Question

Originally reported on Google Code with ID 88

tr1/functional_hash.h and tr1/hashtable.h are both listed as public. However, looking
at the comments of those headers it's pretty clear they they are intended to be private
headers, see:

Thanks!

I noticed you just marked the two headers as private -- do they map to a public header
somewhere?

I'm not sure what IWYU's policy is if all defining headers are private... Could you
test with a simple .cc file like this;

  #include <tr1>
  #include <tr1>

  std::hash<int> h; // from functional_hash.h
  std::_Hashtable<...> ht; // from hashtable.h

I'm guessing the expected behavior here is to replace both #includes with <tr1>.


</tr1></...></int></tr1></tr1>
